A novel single-cell NAD-ME C₄ subtype integrated with CAM and bicarbonate use in an aquatic plant. [PDF]

New Phytol
Summary Many plants maximize photosynthesis by using a CO2‐concentrating mechanism (CCM). Based on physiology, the freshwater plant Ottelia alismoides has three CCMs: C4 metabolism (NAD‐malic enzyme (NAD‐ME) subtype) and bicarbonate‐use during the day plus crassulacean acid metabolism (CAM) at night and lacks Kranz anatomy. Here, we combined a range of

Unravelling the Significance of Phosphoenolpyruvate Carboxylase in Phosphate Starvation Responses. [PDF]

Plant Cell Environ
ABSTRACT Low phosphate availability is a major concern for agriculture. Plants develop a plethora of responses to improve phosphate acquisition, known as phosphate starvation responses (PSR). Among them, the induction of phosphoenolpyruvate carboxylase (PEPC) has been described in many plants. However, most studies have been conducted in the absence of

Comprehensive Analysis of Malate Accumulation in Peaches in Response to Cold Stress Based on Transcriptomics. [PDF]

Food Sci Nutr
This study explored malate‐accumulation mechanisms in “Hujingmilu” peaches under different storage conditions. Low temperature (LT) delayed firmness decline and maintained higher malate. Transcriptomics showed malate biosynthetic genes weakly correlate with malate levels, while proton pump and transporter genes were up‐regulated under LT.

Phosphate Resupply Differentially Impacts the Shoot and Root Proteomes of Arabidopsis thaliana Seedlings. [PDF]

Plant Cell Environ
ABSTRACT Phosphate (Pi) is an essential macronutrient for plant development that is often limited in soil. Plants have evolved dynamic biochemical, physiological and morphological adaptations to cope with Pi deficiency, known as the Pi starvation response (PSR).

Bacterial-type Phosphoenolpyruvate Carboxylase (PEPC) Functions as a Catalytic and Regulatory Subunit of the Novel Class-2 PEPC Complex of Vascular Plants [PDF]

Journal of Biological Chemistry, 2009
Phosphoenolpyruvate carboxylase (PEPC) is a tightly regulated anaplerotic enzyme situated at a major branch point of the plant C metabolism. Two distinct oligomeric classes of PEPC occur in the triglyceride-rich endosperm of developing castor oil seeds (COS).

Increased ethylene production by overexpressing phosphoenolpyruvate carboxylase in the cyanobacterium Synechocystis PCC 6803

Biotechnology for Biofuels, 2020
Background Cyanobacteria can be metabolically engineered to convert CO2 to fuels and chemicals such as ethylene. A major challenge in such efforts is to optimize carbon fixation and partition towards target molecules.

Expression Profiles of Phosphoenolpyruvate Carboxylase and Phosphoenolpyruvate Carboxylase Kinase Genes in Phalaenopsis, Implications for Regulating the Performance of Crassulacean Acid Metabolism

Frontiers in Plant Science, 2018
Phalaenopsis is one of the most important potted plants in the ornamental market of the world. Previous reports implied that crassulacean acid metabolism (CAM) orchids at their young seedling stages might perform C3 or weak CAM photosynthetic pathways ...

Comparison of the effects of nitrogen-, sulfur- and combined nitrogen- and sulfur-deprivations on cell growth, lipid bodies and gene expressions in Chlamydomonas reinhardtii cc5373-sta6

BMC Biotechnology, 2023
Background Biofuel research that aims to optimize growth conditions in microalgae is critically important. Chlamydomonas reinhardtii is a green microalga that offers advantages for biofuel production research. This study compares the effects of nitrogen-,

Functional Analysis of the Phosphoenolpyruvate Carboxylase on the Lipid Accumulation of Peanut (Arachis hypogaea L.) Seeds

Journal of Integrative Agriculture, 2013
Phosphoenolpyruvate carboxylase (PEPC; EC 4.1.1.31) catalyses phosphoenolpyruvate (PEP) to yield oxaloacetate, which is involved in protein biosynthesis.
